Description

Technical Field

[0001] This utility model relates to the field of gas transmission technology, and in particular to a pressure fluctuation buffer component for gas transmission pipelines. Background Technology

[0002] In the actual operation of gas transmission systems, pressure fluctuations constrain system stability. When sudden pressure fluctuations occur in the pipeline (such as instantaneous compressor loading or sudden shutdown of terminal gas-using equipment), these pressure fluctuations propagate within the pipeline at the speed of sound, impacting pipes, welds, instruments, valves, and terminal equipment. This can lead to equipment fatigue damage, measurement distortion, seal failure, and even safety accidents. Because gas transmission pipelines occasionally experience large pressure fluctuations, conventional buffering structures often leave residual pressure fluctuations after buffering, resulting in ineffective buffering. Utility Model Content

[0012] Furthermore, a vent valve is provided at the end of the buffer tank away from the gas delivery pipeline.

A support spring is sleeved on the support column between the pressure cap and the support plate. An external thread for adjusting the height of the support plate is disposed on the top of the support column. A pressure relief chamber is disposed between the pressure cap and the support seat.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0026] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Please refer to Figures 1-2 An embodiment of this utility model provides a pressure fluctuation buffer component for a gas transmission pipeline, comprising:

[0028] Buffer tank 1 is connected to one side of gas delivery pipeline 5, and a buffer chamber 11 is provided inside it;

[0029] Adjustment component 2 is located at the end of buffer tank 1 away from gas delivery pipeline 5, and is used to adjust the effective volume of buffer chamber 11;

[0030] The pressure regulating component 3 is connected to one side of the buffer chamber 11 and is used for instantaneous pressure relief of the buffer chamber 11.

[0031] In this embodiment, when a large pressure fluctuation occurs in the gas delivery pipeline 5, the regulating component 2 increases the effective volume of the buffer chamber 11 inside the buffer tank 1, thereby achieving effective pressure fluctuation buffering with good buffering effect and excellent adaptability. When the instantaneous pressure fluctuation is too large, the pressure regulating component 3 instantaneously releases the gas pressure in the buffer chamber 11 to reduce the impact of pressure fluctuation, further improving the buffering effect of the buffer tank 1 and ensuring the stability of the gas delivery system operation.

[0032] In a preferred embodiment, such as Figure 1 As shown, a connecting pipe 12 is connected to one side of the gas transmission pipeline 5. The connecting pipe 12 is connected to the buffer tank 1 through a flange 13, which is convenient to install and has a stable connection.

[0033] In a preferred embodiment, such as Figure 1 As shown, an electric control valve 4 is installed on the connecting pipe 12. When pressure fluctuations occur, the electric control valve 4 opens, connecting the buffer tank 1 to the gas delivery pipeline 5 to regulate the pressure fluctuations. Under normal circumstances, the electric control valve 4 is in the closed state and does not affect the normal transmission of gas.

[0034] In a preferred embodiment, such as Figure 1 As shown, a pressure sensor is installed on the gas delivery pipeline 5 upstream of the buffer tank 1. The pressure sensor and the solenoid valve 4 are both electrically connected to the microcontroller. The pressure sensor monitors the pressure fluctuations in the gas delivery pipeline 5, and then controls the opening and closing of the solenoid valve 4 and the adjustment of the effective volume of the buffer chamber 11 according to the pressure fluctuations.

[0035] In a preferred embodiment, such as Figure 1 As shown, the adjustment assembly 2 includes an adjustment disc 21 and a drive cylinder 22. The adjustment disc 21 is slidably disposed inside the buffer tank 1. Two first sealing rings 23 are provided between the outer periphery of the adjustment disc 21 and the inner wall of the buffer tank 1. The drive cylinder 22 is fixedly disposed at the end of the buffer tank 1 away from the gas delivery pipeline 5. Its piston rod extends into the buffer tank 1 and is fixedly connected to the adjustment disc 21.

[0036] In this embodiment, the drive cylinder 22 drives the adjusting disc 21 to move within the buffer tank 1 through the extension and retraction of the piston rod, thereby changing the effective volume of the buffer chamber 11. When the pressure fluctuation in the gas delivery pipeline 5 is large, the piston rod retracts to increase the effective volume of the buffer chamber 11, thus effectively buffering the pressure fluctuation.

[0037] In a preferred embodiment, such as Figure 1 As shown, a vent valve 14 is provided at the end of the buffer tank 1 away from the gas delivery pipe 5, which can ensure the smooth movement of the regulating plate 21 and prevent external dust from entering the buffer tank 1.

[0038] In a preferred embodiment, such as Figure 1 and Figure 2As shown, the pressure regulating assembly 3 includes a pressure regulating seat 31 fixedly disposed on one side of the buffer tank 1. A support seat 32 is fixedly disposed on the top of the pressure regulating seat 31. A pressure cap 33 is disposed on the top of the support seat 32. A support column 34 that slides through the pressure cap 33 is fixedly disposed on the top of the support seat 32. Guide columns 35 that slide through the pressure cap 33 are symmetrically disposed on both sides of the support column 34 on the top of the support seat 32. A support plate 36 is slidably sleeved on the top of the support column 34 and the guide column 35. Nuts 37 are threadedly connected to the top of the support column 34 and the guide column 35 above the support plate 36. A support spring 38 is sleeved on the support column 34 between the pressure cap 33 and the support plate 36. An external thread for adjusting the height of the support plate 36 is provided on the top of the support column 34. A pressure relief chamber 39 is provided between the pressure cap 33 and the support seat 32. A pressure relief channel 310 communicating between the buffer chamber 11 and the pressure relief chamber 39 is provided in the pressure regulating seat 31.

[0039] In this embodiment, when the instantaneous pressure in the buffer chamber 11 is too high, the gas enters the pressure relief chamber 39 through the pressure relief channel 310 and pushes open the pressure cap 33 to discharge, achieving the purpose of pressure relief, thereby reducing the pressure in the buffer chamber 11 and improving the buffering effect of the buffer chamber 11. Rotating the nut 37 can adjust the height of the support plate 36, thereby adjusting the elastic support force of the support spring 38, realizing the adjustment of the pressure relief pressure, with good adaptability.

[0040] In a preferred embodiment, such as Figure 1 As shown, a second sealing ring 311 is respectively fitted inside the pressure cap 33 on the outer periphery of the support column 34 and the guide column 35 to ensure the sealing between the pressure cap 33 and the support column 34 and the guide column 35; a third sealing ring 312 is provided on the outer periphery of the pressure relief cavity 39 between the pressure cap 33 and the support seat 32 to ensure the sealing between the pressure cap 33 and the support seat 32.
